Determination of Resilient Properties of Unbound Materials with Repeated Load Triaxial and Diametral Test Systems
Repeated load diametral test systems are experiencing increased use to determine resilient properties of asphalt concrete and admixture stabilized materials; they have not been used extensively to determine the resilient properties of unbound materials. This is due in part to the fact that comparative studies between the properties obtained with the diametral test system and the repeated load triaxial test system have not been made. In response to the need to establish a correlative data base between resilient properties determined with diametral and repeated load triaxial test systems, a laboratory test program was conducted. Specifically, resilient properties of two-base course and two subgrade materials were determined using both repeated load triaxial and diametral test systems. The differences between resilient moduli determined with either the diametral or triaxial test system led to negligible differences in the design thickness of materials in representative pavement structures.
